Israeli President Shimon Peres meets with U.S. President Barack Obama in Washington Tuesday to discuss the best approach for peace with the Palestinians, and how to deal with Iran.

On Monday, Mr. Peres addressed the American-Israel Public Affairs Committee, or AIPAC, without referring to proposals for creating a separate Palestinian state.

Meanwhile, Israeli Prime Minister Benjamin Netanyahu called for a fresh approach to peace with the Palestinians.

Mr. Netanyahu spoke Monday through a satellite video link from Jerusalem to the annual AIPAC convention in Washington. He described what he called a triple-track approach that addresses political, economic and security issues related to the peace process.

Palestinian statehood has been the centerpiece of U.S. mediation efforts in the Middle East for most of the past decade.

Mr. Peres said Monday that Iran's nuclear activities threaten the United States, Europe and Arab nations, as well as Israel.

Iran says its nuclear program is only for civilian use and that it has a right to develop such technology. The United Nations, prompted by the concerns of the U.S., European nations and others, has imposed three sets of sanctions on Iran because of the nuclear program.
